When purchasing your plants go straight home and don't leave them 'cooking' in a hot car while you finish your shopping. Water your plants thoroughly when you get them home and keep them somewhere relatively cool in the shade until you plant them.
The next point may seem obvious but I too have been guilty of this – Don't leave the plants in their pots for months until you find that mythical bit of extra time because they may not survive that delay. Plant them now!
Planting Trees & Shrubs
Select the planting spot. Read the label so you know which conditions eg sun or shade, the plant prefers, also any other special treatment that may be required.
It is advisable to soak the area the day before planting, ensuring a high soil moisture level for the plants. Improve the soil if necessary. If it is poorly drained you may need to create a raised bed. If poor drainage is due to clay soil type, applications of gypsum will contribute to improving the friability and structure of clay soil.
Dig a hole that is about the same depth as the pot or container and about twice as wide. Mix in some good quality compost and long-term fertiliser tabs. These provide gentle non-burning nutrients for the roots. Thoroughly water the potted plant again and remove it from the pot. If roots are circling around the outside, loosen them with your fingers.
This will encourage root growth into the surrounding soil rather than roots continuing to twine in a ball, limiting plant growth. However do not apply this practice to avocados, pittosporums or members of the proteace family (proteas, leucadendrons & leucospermums) which are very sensitive to root disturbance.
Make sure the plant is at about the same planting depth as it was when in the pot or container. Water well, this settles the soil into place as well as moistening the roots.
Check for any spots where the soil level has dropped and top up with more soil. Water finds it harder to move into an established root system than into soft surrounding soil. Encourage the water to get in where it is needed by adding saturaid which is a rewetting granule to keep plants evenly moist; then water again.
Lastly apply a good layer of organic mulch over the root area. Don't let it contact the trunk or base of the plant. Remember to keep the root area moist over the next few months especially if it is hot, dry or windy.
Happy Gardening!
